So I've got a broken P3P camera. I have sent the camera in for repair, but I was thinking of either buying a spare camera for $349 so I don't have to be "down", but it looks like I can get a P3 4K for $599, with a controller and a drone. Seems like it would be kind of silly to spend $350 on a spare camera at that point. Other than the frame rate on the 4k camera, is there much in the way of a difference between the professional and the 4k?
